Abdominal Pressure/Lactation

I'm 21 weeks . Last night a clear liquid was coming from my breasts & my doc said it was a-okay which is good.
However , i've had a lot of uti in my day so when i started getting pressure in my abdomen I went to my urologists & was told i was fine, no infection. But i still have lots of lower ab pressure especially when i go to pee. Is this normal just because my uterus is getting so big. It's a boy too (which i heard sit lower than girls) & hes already head down. Just want some reassurance from more experienced mom's because this is all new for me.

I used to get bladder infections a lot before I got pregnant. I would get the same odd pain that I had when I had an infection while pregnant. I didn't ever have a uti or a bladder infection though. It was just dd pressing on stuff.

im having a girl and she is super low and head down and i always have that pressure feeling even when i pee lol im 24 weeks with 36 week preemie babies that r 4 and 1. i had these same things with them but more when i was in my 30 weeks and up. this time i think its cuz she is low.
